Active and Passive Plasmonic Devices for Optical Communications
A short introduction to the theory of surface plasmon polaritons (SPPs) is given. The application of the SPPs in on-chip signal processing is discussed. In particular, two concepts of plasmonic modulators are reported, wherein the SPPs are modulated by 40 Gbit/s electrical signals. Phase and Mach-Zehnder modulators employing the Pockels effect in electro-optic organic materials are discussed. A few micro-meter long SPP absorption modulator based on a thin layer of indium-tin-oxide is reported
Active and Passive Plasmonic Devices for Optical Communications
In this book, novel plasmonic devices are designed and demonstrated. In particular, an ultra-compact phase modulator is reported by exploiting plasmonics and Pockels effect in electro-optic organic materials. An absorption modulator with a length of few micrometers is designed and demonstrated. To efficiently interface plasmonics with low loss silicon photonics, novel photonic-to-plasmonic mode converters were developed. Finally, a new ultra-compact polarization beam splitter (PBS) is presented
Silicon-organic hybrid (SOH) integration and photonic multi-chip systems: Technologies for high-speed optical interconnects
Limitations of silicon photonics can be overcome by hybrid integration of silicon photonic or plasmonic circuits with organic materials or by photonic multi-chip systems. We give an overview on our recent progress regarding both silicon-organic hybrid (SOH) integration and multi-chip integration enabled by photonic wire bonding
Single-laser 32.5 Tbit/s Nyquist WDM transmission
We demonstrate 32.5 Tbit/s 16QAM Nyquist WDM transmission over a total length
of 227 km of SMF-28 without optical dispersion compensation. A number of 325
optical carriers are derived from a single laser and encoded with
dual-polarization 16QAM data using sinc-shaped Nyquist pulses. As we use no
guard bands, the carriers have a spacing of 12.5 GHz equal to the Nyquist
bandwidth of the data. We achieve a high net spectral efficiency of 6.4
bit/s/Hz using a software-defined transmitter which generates the electrical
modulator drive signals in real-time.Comment: (c) 2012 Optical Society of America. One print or electronic copy may
